Key Features
147-grain FMJ-BT projectile – Full metal jacket construction supports reliable feeding, while the boat-tail profile helps maintain stability and reduces drag at distance.
M80-style role – Bullet weight and general performance align with common 147-grain “ball” expectations for 7.62 NATO training use.
24-inch test-barrel ballistics – Published velocity is 2,800 fps with 2,611 ft-lbs of muzzle energy from a 24-inch barrel reference.
Longer-range consistency – Listed ballistic coefficient and bullet form are intended to support predictable drop and wind behavior compared with flat-base FMJ designs.
Training and function focus – Designed for repeatable cycling and practical accuracy rather than controlled expansion.
